The Magnuson Upgraded HEAVY DUTY Tensioner is a MUST-HAVE upgrade when running at higher
boost levels. Most customers running over 8psi have experienced issues with
the standard tensioner that comes with the supercharger kits. At standard loads,
running at 7 or 8 psi, the stock tensioner is fine, however, we have found that
when you start getting up to the 10-15 psi range with the smaller pulleys slip
and belt fatigue (and failure) occur. This tensioner has an 8-rib pulley with
a stronger arm and spring to reduce slip and breakage under the heavier loads
produced at higher boost levels.
